Alliances can select the midpoint of their vulnerability window, which is called their "Default Sovereignty Vulnerability Time", or prime time (see below).

The vulnerability window is centered on the selected vulnerability time and scales in both directions.

Example: A structure vulnerability window lasts for 2 hours.

The exact duration of the vulnerability window is locked in at the selected vulnerability time the day before.

This stage is known as the “Windows of Opportunity” or “Critical Period” stage.

Offllining the structure will immediately put it into a 2 hours vulnerability window.

For example, if the vulnerability window is 4 hours and prime time is set to 16:00 then the vulnerability window will be from 14:00 to 18:00.

We showed that there is a window of opportunity – the first 1000 days of life.

Structures that are claimed during the alliance vulnerability window will become vulnerable immediately for the remaining duration of the window.

The form this toxicity takes depends on the period concerned: we call this the window of vulnerability.

It will exit reinforced mode at a randomly selected time during the next vulnerability window.

Every minute a waiting for a virus signature update creates a window of vulnerability that could have devastating consequences.

This localized expansion offers a very brief window of vulnerability before the virus efficiently establishes a systemic infection.

A system with Military and Industrial each at 1 would already have shrunk its vulnerability window all the way to 8.18 hours.

Security patches are automatically applied every quarter or as needed, narrowing the window of vulnerability.
